In general, platinum is not a better investment than gold. Gold is more stable, is more easily mined, and its price doesn't fluctuate as much as platinum. And the value of gold is considerably greater than that of platinum. In the end, precious metals have their uses as investments, and gold is often considered the best place for a Gold IRA. When political or economic uncertainty hits, investors often turn to alternative or tangible assets to protect their portfolios.
Precious metals such as gold are just one option available to you. However, all investments come with risks. Platinum has higher volatility than other options, making it more susceptible to price drops. Meanwhile, gold remains relatively stable, but it may not be a solid hedge against short-term inflation.
Like gold and silver, platinum is traded 24 hours a day on global commodity markets. It tends to reach a higher price (per troy ounce) than gold during routine periods of political and market stability simply because it is much rarer. In fact, much less metal is extracted from the ground every year. While gold is a big investment, the cost of buying significant amounts of gold can be a bit prohibitive for some newer investors.
On the other hand, American gold coins minted before the elimination of circulating gold in 1933 may have more than half of their total price linked to their value as collectibles.
